UNION — The search resumes today for the body of a woman believed to have been killed by her boyfriend, authorities said.

April Wyckoff, a 43-year-old mother of two from Cranford, is still being sought by detectives from the Union County Prosecutor's Office, said Mark Spivey, a spokesman for the office.

New Jersey State Police helicopters are assisting the search this morning, Spivey said, adding that the area of the search is somewhere in the northern part of the state, but declining to further specify.

Matthew Ballister, Wyckoff';s 43-year-old boyfriend, remains in the Union County Jail on $2 million bail on the murder charge, the jail confirmed this morning.

Ballister's mother, 70-year-old Eleanor Schofield of Mountainside, is also held at the jail. She is charged with hindering apprehension for allegedly concealing evidence in connection with the killing, authorities said. Schofield is held on $1,500 bail, a corrections official said today.

Ballister killed Wyckoff sometime Tuesday night in his Mercer Avenue home, then tried to cover up the crime with the help of his mother, authorities said.

Police responded to the split-level home with guns drawn on Wednesday afternoon, neighbors said. For most of Thursday, investigators continued to pull items out of the home and bag them as evidence.

Wyckoff had a black eye that she attributed to falling over a dog as recently as Oct. 10, a Wyckoff family member said. Neighbors and that family member said that the divorced woman had taken a restraining order out against Ballister, her boyfriend – but that she had moved back to the house at some point.

The victim's former father-in-law said the surviving family, especially Wyckoff's 16-year-old daughter and 23-year-old son, were devastated by the turn of events this week.

"The family’s taking it bad," said James Wyckoff, the ex-father-in-law.
